Patented Nov, 12, 1940 UNITED STATES This invention relates tostrip m eta l coiling 'machines]and, particularly, to an improved means for delivering the coi1s,ther efrom.'

Coils of strip metal are very large and heavy 5 and it is impractical; as well as dangerous, to remove these coils manually fromthe' coiling machines. Consequently, various methods and devices have been used and suggested for removing the coilsof metal'from the coilers: Some 10 of these have. been satisfactory, but most of them have been unsafein their use or too expensive 'andcomplicated to employ.

According to the present invention,lthe metal coils canbe easily andquickly removed from the coiling machineswith a minimum amount "of dangerie a @It is one of the objects of the present inven tion to provideqan, improved means for safely removing strip coils of metal from the coiling machines. 1

h It is another object of the inventionito 'pro vide an improved device for removing coils from the ceiling machines which willalso aidin the coiling thereof.

It is a further objeo tof the invention to pro vide an improved device for removing coils of metal from the coiling machinewhich. has part of its mechanism controlled by the coil as it,

passes thereover,ithereby makingit semi-automatic injits operation, H Various otherobjects and advantages of this invention'will be more apparent in thelcourse of the following specification andwillbe particularly pointed out in the appended claims.

Inthe accompanying drawingsgthere is shown,

for the purpose of illustration, one embodiment which my invention may assumein practice.

In these drawings:

Figure 1 isa plan of there is shown a coiling machine} withwhich my invention may be, incorporated, having a pair of end housings 3, upwardly extending end walls 50 ,4, and a coiler push-out mechanism 5.

According to the present invention, there is,

positioned, on the deliveryf side of the coiling machine, an outwardly inclined stationary plat- .form 6 having a longitudinally extending, circu 55' lat-shaped slot or channel 1 arranged therein, the

h the improv d c o il delivering deviceof my invention positioned on the,

Figure, 3 is a section taken on line III-III of or bar 35.

PATENT purpose of which will be described later in the specification, and a if-shaped, slot 8 adjacent the front end thereof for the purposeof receiving bolts for theattachment ofside coil guides? which can be adjusted to the properposition on the platform relativejto the width of the coil.

There is arranged, between the stationary platform 6 and the coilingmechanismor rolls of the coiling machine, a retractable platform exten- 1 sion 9 Whichis keyed or otherwise seouredto a shaft H1 extending between thejend housings 3 of 3 h the machine and pivotally supported thereby.

The stationary platform 6 is supported at one side by the shaft lll" and, at the otherside pre-, ferably by an I-beam l2, but it will be undera stood that any suitable supporting means may i There is arranged on the shaftfilfl and keyed thereto a pair ofarms l3, on-e'adjacenteach end thereof, having a guidirigmeans such as a roller, H, rotatably mounted therebetween. At one end' of the machine, beyond a platfoi msupporting arm l5, there is also positioned on the'shaft, I0 and keyed thereto, a lever arm l6 having ,a, counterweight [l1 arranged thereon, and at the other end of theshaft, bey'on'da platform supporting arm l8, there is positioned thereon and keyed thereto; a bell-crank l9, one arm of which is attached to a conneoting-rod 20 and th eother arm thereof adapted to ,contact an adjustablei stop-screw 2| suitably positioned on the end housing of the machine. The connecting-rod 2|] is attached /to a piston 22 of an air-cylinder 23 suitably po itioned below the platform 6. There is arrange in the air-cylinder 23 on theconnecting-rod 20 a compression coil spring, 24 which is adapted to act between the piston and a flanged portion of the air cylinder extension 25.

There is ipositioned on the under side ,of the stationary platform 6,just beyond and below the slot 1, a shaft 26 which is, pivotally mountedin the end walls thereof. There, is arranged on each endof the shaft 26, andkeyed thereto, a trigger ,crank 21 having one arm 28on which there is positioned a counterweight" 29, an op-" positely disposed arm 30' having an adjustable stop-screw 3lfarrangecl' in the end thereof which is adapted to contact the under side ofthe'beam I2 or some other portion of the platform Sfan upwardly extending arm 32 having a latch-catch 33 arranged thereonan d having an outwardly and upwardly extending offset .portion 34. There is arranged between the ends of the two offset portions 34 of the arms 32 an angle arm This improved coil delivery device of my invention operates as follows:

It will be assumed that the strip has been coiled in the coiling machine and the metal coil is ready to be delivered therefrom. As the strip is being coiled, theretractable platform extension Sgtogether with the arms l3 and the roller l4,

will assume the position as shown in Figure 2, with the roller 14 positioned in slots36 arranged in the back of the end walls 4 of the coiling machine. In such a position, theplatform extension is retracted and out of the path of the moving strip being coiled and the roller closes the open delivery side of the coiling chamber of the machine, thereby preventing the coil from accidentally getting out of control and leaving the.

machine. These parts are retained in this position by the air-cylinder 23; that is, the air is. turnedon, forcing the piston 22 upwardly, com

form 6. j Thesev parts are'moved to thisposi ,tion through the action of the coil spring. 24 and the counterweight II.,.As the arms I3'are moved tothis position, latch-blocks 37, carried by the ends thereof, ,engage "with the latchcatches 33 .carried by the arm'32 of the trigger crank, thereby locking these arms and the associatedmechanism in this position. The air pressure is then again turned on in the air-cylinder 23, tending to force the piston 22 upwardly.

' Thecoii "of metal is then ready .to be released from the coiling machineand is forced thereout by means of the pushout mechanism 5, as shown, or any'other suitable mechanism, onto the retractable platform extension 9. The coil then rolls over this extension onto the platform 6 and, as it rolls thereover, finally treads over the bar 35, forcing it downwardly, thereby rotating the shaft 26 in a counter-clockwise direction, disengagingthe latch-catches 33 and latch-blocks 31 and permitting the arms 13 to be returned to their original .position, as shown in Figure2,

' ready for the next coiling operation." It will be seen that as the armsil 3, together with the roller H, are forcefully returned to positiomdue to the air pressure against the piston in the aircylinder,'the roller I4 contacts the back under sidejof the coil, thereby giving it a forceful push to hasten its delivery therefrom,

I as indicated by the broken lines in Figure 3.

As a result of my invention, it will be seen that v I have provided a simple and inexpensively constructed means for quickly and safely, removing the coils of strip metal from the coilingmachine.

While I have shown and'describedan embodiment ofmy invention, itwill be understood that this embodiment is merely for the purpose ofv illustration and descriptionfand'that various other forms may be devised within the scope of my invention, as defined inthe'appended claims.
